A single goal from Alex Calvo-Garcia was enough to take Scunthorpe up to the Second Division after a frenetic 90 minutes at Wembley.

The Spaniard's glancing header from Gareth Sheldon's cross separated the sides from the sixth minute until the final whistle.

It meant jubilation for manager Brian Laws in only his second season at Glanford Park in front of a crowd of 36,985.

Brighter from the start, Scunthorpe deserved their win after creating the better chances on a hot afternoon in North London.

Scott Barrett needed to be alert to save from Andrew Dawson, and the same player nearly added a second shortly after, his curling 25-yard free-kick flying just wide.

Captain Chris Hope nearly got in the act, heading over following a corner and Leyton Orient, backed by snooker and boxing promoter Barry Hearn, were struggling to get into the game.

Their best efforts came from Matt Lockwood who shot wastefully on two separate occasions.

Orient manager Tommy Taylor tried to change things at half-time, bringing on former Southampton player Craig Maskell and Alex Inglethorpe for Tony Richards and Stuart Hicks.

The change forced Scunthorpe goalkeeper Tom Evans into his first serious action of the afternoon, saving from Amara Simba, Orient's 37-year-old former French international.

Jamie Forrester, the former Leeds United player, sent two curling efforts just wide in quick succession, while at the other end referee Clive Wilkes turned a deaf ear to a penalty appeal, correctly judging Russ Wilcox had won the ball when he challenged Martin Ling in his own
area.

On the hour, Orient created their best chance of the game, Steve Watts sending Maskell's cross towards the net, until Evans intervened, spreading himself to block the shot and Simba then saw his follow-up effort cannon away from the danger zone.

Then, with four minutes left and United desperately hanging on to their lead, sub Alex Inglethorpe was found in space by Simba 12 yards out but his angled drive was parried away by Evans.

Scunthorpe managed to keep their composure during and after those tricky moments and could have sealed things when Darryn Stamp broke clear of the Orient defence, only to see his two goalbound efforts blocked on the line by Martin Ling.
